Everton's Jagielka salutes courageous Cahill
The Socceroos star has been hampered by the injury since returning from international duty at the Asian Cup in January but has remained committed to the cause as the Toffees experience a spate of injuries as they strive to finish in the top six.
"It's great to have Tim back but I don't think he's fully fit. I think he's still got a little bit of pain in his foot," he told Liverpool Echo.
"But the squad's not the biggest at the moment and sometimes we might need him to come off the bench.
"We'll have to play it by ear and see how much he can play between now and the end of the season.
"It's not just his play, it's his character in the changing room."
