Marc Roberts and Che Adams have both picked up hamstring problems, joining Maxime Colin, who is expected to remain sidelined this weekend. Defender Harlee Dean is available after suspension while midfielder Jason Lowe could be pushing for inclusion.

QPR's defensive crisis has eased for the trip to St Andrew's. Alex Baptiste is available after suspension while captain Nedum Onuoha (hamstring) and Grant Hall (knee) both returned from spells out in last weekend's defeat by Leeds.

Steven Caulker played in an under-23 match earlier this week and James Perch (knee) is also back in training. Winger Jamie Mackie serves the second game of his three-match ban.

Opta stats

The Blues have lost two of their last three home league matches against QPR, more than they lost in their previous 22 (one).

Since going on a 14-match winless league run against Birmingham between 1986 and early October 2008, QPR have won five of their last seven against the Blues (D1 L1), including a 4-1 win at St. Andrew's last season.

Birmingham have won only two of their 10 Championship games since Steve Cotterill took charge in October (W2 D2 L6) - only Burton (5) have won fewer points than the Blues in this period (8).

QPR striker Matt Smith has scored four goals and provided two assists in six previous league appearances against Birmingham.

QPR are on the current longest away winless run in the top four tiers of English football (17 league games) - the R's haven't won on the road since beating Birmingham 4-1 back in February.

The Blues have used more players than any other Championship side this season (30).

Prutton's prediction

This is a big, big game for QPR, who could get dragged right back into the relegation battle if they are beaten here. That didn't look at all likely a few weeks ago when they beat Wolves and Sheffield United on their own patch, but their form has deteriorated since.

Birmingham just can't find a goal from anywhere, netting just 10 times in 21 games so far. There are five strikers in the division who have scored more! And because of that I'm going for a dour goalless draw.

David Prutton predicts: 0-0 (8/1 with Sky Bet)
