Crystal Palace manager Alan Pardew criticized referee Mark Clattenburg after Yohan Cabaye was injured in his side's 1-0 FA Cup fourth round win over Stoke.
Cabaye was felled by Stephen Ireland shortly before halftime at Selhurst Park on Saturday but Clattenburg elected to wave play on, with Xherdan Shaqiri going on to fire just over for the visitor.
The France midfielder was substituted at halftime and, while Pardew is hopeful the ankle injury is not too serious, the former Newcastle United boss thinks Clattenburg made an error.
"I thought Mark got that particular decision wrong, because he came in from the side on Yohan and his ankle is swollen," Pardew told reporters.
