Celtic winger James Forrest is out of Sunday's William Hill Scottish Cup semi-final with Hearts at Hampden and doubtful for the rest of the season as he struggles with an ankle injury.

Skipper Scott Brown has a knock and will be assessed while midfielder Victor Wanyama returns from suspension.

Defender Thomas Rogne (knock) and striker Mo Bangura (knee) have both returned to training while midfielder Beram Kayal (ankle) will resume full training on Monday.

Jamie Hamill is absent with a knee injury as Hearts.

Right-back Hamill suffered a cruciate injury in training this week and is likely to miss the start of next season, but winger David Templeton could return for the first time since February following a groin problem.

Defender Andy Webster (thigh) should be fit, but doubts remain over the fitness of striker Craig Beattie (heel), winger Mehdi Taouil (back), midfielder Adrian Mrowiec (knee) and forward Stephen Elliott (hip).
