Adam Matthews is very doubtful for Celtic. The Wales right-back twisted his ankle in training on Thursday and could join midfielders Kris Commons (thigh) and Joe Ledley (ankle) on the sidelines. Defender Kelvin Wilson and Thomas Rogne have recovered fully from their respective Achilles and hamstring injuries and are in contention. Defender Andy Webster is a doubt for Hearts after coming off at half-time in the loss to St Johnstone last weekend with a calf problem. Left-back Danny Grainger is out for around six weeks after undergoing groin surgery, defender Darren Barr (groin) is also missing, while striker Kevin Kyle, forward Gary Glen and winger Suso Santana remain out. Celtic (from): Forster, Majstorovic, Matthews, Cha, K Wilson, Rogne, Loovens, Brown, Kayal, Wanyama, Samaras, Stokes, Ki, Forrest, Hooper, Zaluska, Bangura, McCourt, McGeouch, Filip Twardzik. Hearts (from) Kello, Hamill, Webster, Zaliukas, Mrowiec, Jonsson, Driver, Stevenson, Taouil, Templeton, Robinson, Skacel, Novikovas, Elliott, MacDonald, Obua, MacDonald.
