Nottingham Forest may be without star striker Britt Assombalonga for the remainder of the season.
The 22-year-old requires surgery to establish the extent of his problem, suspected of potentially being a ruptured patellar tendon.
Assombalonga struck in their 3-0 win over Wigan Athletic, but was stretchered off in the 67th minute after falling awkwardly.
If the £5.5m club record signing is sidelined for the remaining 16 games of the Championship, it would be a big blow to manager Dougie Freedman.
