Manchester United manager Louis van Gaal has admitted that Ashley Young faces a long spell on the sidelines.
More from the boss: "But I'm not a doctor so we have to wait for tomorrow or the day after tomorrow." #mufc— Manchester United (@ManUtd) January 1, 2015
Young picked the injury in the second half and was substituted immediately, missing the final 15 minutes of the contest in the process.
United drew the match 1-1 and remain third in the Premier League table with 37 points from 20 matches.
