Donegal captain Michael Murphy hopes he will be fit to play in next month's Ulster championship tie against Cavan.
The 22-year-old is still on crutches after having a scope on the knee injury he sustained against Dublin.
Murphy missed Donegal's win over Armagh on Sunday but insists there is no pressure on him to rush his comeback.
"It's about the rehab now but there are no targets. I'll keep plugging away and we'll see if time allows me to play (against Cavan)," he said.
Murphy damaged lateral ligaments in his knee in the league game against Dublin two weeks ago, having only just returned from surgery on a groin injury in January.
He had a scope in the Sports Surgery Clinic in Santry and watched from the sidelines on Sunday as his Donegal team-mates beat Armagh to retain division one status for next season.
Now the focus has immediately switched to the Ulster championship and Murphy faces a race against time to be ready for the preliminary round tie with Cavan on May 20 in Breffni Park.
"You get injuries, maybe it was unfortunate to get two in-a-row, but that's football," he said.
"There was a scope to check (the knee). I don't know if there was much in there to repair really.
"Hopefully I will get back at the best time possible, whether that is in a number of weeks or a number of months.
"To be quite honest I am very lucky that Jim McGuinness and Rory Gallagher aren't putting me under any pressure, so it's just a matter of coming back when it's fully healed.
"I have been given the rehab programme and whenever the time is right to come back and get playing football again, then that's when it will be.
"Jim and everyone else are on the same wavelength about that."
