Substitute Sullay Kaikai grabbed an equaliser late on to earn Richard Money's Cambridge a 1-1 draw at high-flying Shrewsbury.Micky Mellon's men started brightly and Tyrone Barnett was unfortunate to see his shot from the edge of the box rattle the bar. But Cambridge never cleared the danger and when James Collins delivered a cross from the right, Mickey Demetriou nodded down for Bobby Grant to fire home a low shot from 18 yards to give Shrewsbury a 16th-minute lead. Cambridge responded positively and the dangerous Jordan Slew twice forced keeper Jayson Leutwiler into sharp saves. Then Shrewsbury were indebted to a fine clearance from Cameron Gayle for denying Matt Harrold a probable equaliser from close range. But Micky Mellon's promotion-chasers were always dangerous and Collins forced a decent save from Chris Dunn with a low shot from distance on the stroke of half-time. Dunn made good stops from Jordan Clark and Grant also hit the bar as Shrewsbury strived to add to their lead in the second half. But Cambridge never gave up and Leutwiler had been forced to make several decent stops, the pick of them from Josh Coulson's point blank header before the visitors were finally rewarded with time almost up. Shrewsbury failed to clear and substitute Kaikai finished coolly from 12 yards to earn Cambridge a hard-earned point which knocks the Shrews off top spot in League Two.
