Adam Matthews admits he is happy to be back playing again despite Aberdeen wrecking hopes of another double.
Matthews and his Celtic colleagues exited the Scottish Cup after a 2-1 home defeat by the Dons, but the Wales full-back was pleased to be be back following a calf injury picked up during the mid-winter trip to Turkey.
"It's been a bad season for me with injuries, so hopefully I can now put them behind me and get a good run of games now," he told Celtic View.
"The calf is feeling good now, the shoulder is feeling good, so hopefully I can keep training hard, get fit and help the team.
"I think it was my last sprint back before I was coming off, and I felt a twinge in my calf. I didn't think anything of it, but went for a scan when I came home, and it was a Grade 2 strain.
"Obviously it was bad timing, especially getting injured in a friendly, but hopefully I can put that behind me.
"It is frustrating. It took me a while to get back to where I wanted to be and I felt with the run of games I was getting, that I was getting close to it. It was bad timing, so starting again, getting fit again hasn't helped, but you get that in football so hopefully I can stay injury-free for the rest of the season."
Next up for Celtic is a home game against St Johnstone in front of the Sky Sports cameras on Sunday, with the Hoops aiming to preserve their unbeaten league record this season.
"They'll be well-organised," he added. "They'll sit in and they're always hard to break down so we know that we'll have to be at our best to hopefully get the win.
"But St Johnstone always give us a tough game, and they've got some good players who can hit us on the counter-attack so we have to be at our best all over the pitch."
