A new father and some former Super Rugby stars feature in our team of the week along with a World Cup winning fly-half.
Scarlets beat Ulster 21-20 in Belfast, a victory that put Scarlets in third place in the PRO12 standings, and Michael Collins played a big part in the victory.
He scored Scarlets' two tries, and carried 13 times for 134 metres. The full-back beat four defenders on his runs, causing havoc for the Ulsterman in front of the Kingspan faithful.
He may not be eligible for Guy Noves' national side but the blistering winger is a must-selection for our team of the week.
Smith played in the No 11 jersey on Saturday but he was all over the park in Castres' 27-17 loss to Clermont, so we've put him on the right wing in our team.
He carried nine times on the day, making 121 metres at an average gain of more than 13 metres per carry. France will rue World Rugby's eligibility rules.
There was plenty of action in the midfield when Stade Francais beat Brive 32-17, and Nayacalevu was at the heart of the comeback that allowed for the Paris side's win.
For the first try he sent a long pass out wide to Djibril Camara for the winger to score in the corner, and for the second he showed a much lighter touch with an offload out of the back of the hand to Hugo Bonneval who sent Jeremy Sinzelle racing away for the score.
The midfielder was not only influential with ball in hand - he also put in the most tackles out of the Stade Francais backs.
Marshall has been in excellent form this season and continued to stake his claim for a centre berth with Ireland with another fine all-round display against Scarlets.
Marshall threw a great pass under pressure to release Craig Gilroy for his fantastic try and the 24-year-old scored Ulster's second when he combined with namesake Paul and showed great pace and power to beat three defenders and touch down in the corner.
Marshall gained 87 metres from 16 carries and also put in a shift in defence, making nine tackles and winning one turnover.
Zebre put up a fight in Italy, scoring four tries as they amassed 34 points against Connacht, but the men from Ireland put a half century up on the board with six tries - and three of them came from winger Healy.
He showed superb speed and good vision for the hat-trick, with his first try in particular showcasing his skills.
Colin Slade scored all of his side's points as Pau recorded a 19-16 victory over their Top 14 rivals, but more impressive was the way he went about it. With 10 minutes remaining Pau were trailing by seven points when they were awarded a kickable penalty by the referee.
Ignoring the coach and captain's orders to go for poles and grab a losing bonus point, Slade kicked for touch, and on the back of the lineout scored a try which he converted. He later slotted the match-winning penalty.
After the game Pau coach Simon Mannix put the decision down to a communication breakdown due to the former All Black's poor French, but Slade was not about to hide behind the decision, stating: "I play the game to win."
Hougaard was announced as Worcester's new signing less than a week ago and he showed himself to a shrewd acquisition by the Warriors with a try-scoring debut as Worcester ran out 31-23 winner over Sale Sharks at Sixways.
Hougaard had an influential debut for Warriors, with and without the ball, earning coach Dean Ryan's praise.
"He only arrived on Monday, but Francois was outstanding today," the Worcester boss said. "He's a class player and his confidence spread through the team."
Jack McGrath has been in good form for Ireland but Cian Healy sent out a reminder of his capabilities over the weekend. Besides providing power up front the loosehead prop also threw himself into 15 tackles.
He also brought about a turnover and pitched in with seven carries - tied third for the most in the Leinster side.
One lost lineout out of nine was the only real blemish on Myhill's report card as he put in a big shift for the Welsh side.
Eight successful lineouts were overshadowed by the 20 tackles he put in during an arm-wrestle that was fought out up front.
A Schalk Brits red card threatened a second successive loss at Allianz Park for Saracens but the wolfpack delivered another unified performance to grind out a 25-12 win over Gloucester.
But that wasn't the only good delivery for the team on Saturday, as front-rower Juan Figallo's son was born on the morning of the match.
The prop forward made sure that all was well with his wife and child before dashing off to the Saracens ground to help his side claim the victory.
Bulbring and his second row partner George Earle were superb for Scarlets on Sunday, but Bulbring makes it into the team for his 16 tackles.
It was a game that was on a knife-edge for large portions, so defensive precision was a requirement and Bulbring led the Welsh forwards in that category in Belfast. He also effected a turnover, and carried well for third-place side.
Vahaamahina was the all-rounder of the Clermont pack this weekend. Not only did he take every lineout ball thrown to him, but stole one from the Castres throw too.
He marshalled the driving maul, carried the ball seven times, was tied third for the most Clermont tackles on the day and also won his side a turnover.
Horrendous conditions welcomed Leinster and the Cardiff Blues in a 14-13 win for the visitors. It was not one for glamour but Rhys Ruddock stood head and shoulders above the rest for one statistic in particular.
The loose forward put in 29 tackles on opposition ball carriers, stopping constant threats from the Blues as they tried to muscle their way back into the game.
Ruddock also turned the ball over for his side and carried eight times to cap off a tiring day at the office.
Wasps knew all too well the challenge that lay before them when they visited the Rec to play Bath. It was the fourth meeting between the two sides this season, with Wasps leading the unofficial series 2-1.
It was close at half-time but a pair of Frank Halai tries earned the title contenders an 18-14 win. George Smith was his peerless best on the day, turning the ball over four times as Bath tried to stamp their mark on the game, while also putting in 14 tackles and taking the ball up 11 times.
The Scotland international put in an impressive man-of-the match display as Glasgow did their PRO12 campaign a favour with a 27-24 win over Munster.
Strauss put in 15 tackles and carried nine times for 104 metres. With ball in hand the loose forward beat seven attempted tackles, as Glasgow won to keep their PRO12 hopes alive.
Honourable mention to rising England star Josh Beaumont who was a thorn in the side of Worcester.
