Malik Tillman’s time with Scottish Premiership club Rangers could very well be coming to an end.

Tillman did not dress for Rangers on Sunday after manager Michael Beale ruled him out for the remainder of the league campaign. The Bayern Munich loanee suffered a hamstring injury in Rangers’ 1-0 Scottish Cup semifinal loss to Celtic on April 30 and will now miss the final four matches this spring.

“Malik Tillman has performed well for the club but he will be ruled out for the rest of the season due to injury,” Beale said before Sunday’s match.

Tillman was in tears last weekend after being replaced in the first half Hampden Park following a physical challenge with Celtic’s Greg Taylor. The 20-year-old enjoyed a positive loan spell in Glasgow, scoring 12 goals and registering five assists in 42 combined appearances.

The U.S. men’s national team attacker was recently nominated for Rangers’ Player of the Year award, as well as two additional individual achievements this campaign. Despite Tillman’s best efforts, Rangers watched Celtic clinch the Premiership title on Sunday following its 2-0 road win over Hearts.

Rangers had previously been linked with adding Tillman on a permanent deal from Bayern Munich, with the German giants asking for at least £5 million.

There is no timetable for Tillman’s return to action with the USMNT set for Concacaf Nations League and Gold Cup involvement this summer.
