PETER JACKSON has welcomed Danny Adams' availability after suspension.

But he warned the seasoned left-back that an immediate League I return at Millwall next Tuesday is by no means certain.

Adams, who gained some much needed match practice in yesterday's 2-0 Reserve defeat by Rotherham (report Page 46) has served a four-match ban, during which time teenager Joe Skarz has impressed in his place.

Adams received a three-match suspension for his straight red card in the 3-0 home defeat by Brighton, and had an extra game added because it was his second sending off this season.

Skarz, 17, stepped out of the Academy side to feature in all four matches during Adams' absence.

And while his form dipped, in common with most of the side, as Oldham won 3-0 at the Galpharm last Saturday, he showed enough in the previous three matches to give Jackson a selection dilemma.

"It's a tough one," admitted the manager, who is desperate to kick-start a climb up the table by his 14th-placed side after just one point from the last 12 available.

"Joe has stepped up into the first team at a difficult time and done exceptionally well.

"I'm proud of his displays, and they are testament to the good work being done by Gerry Murphy and Graham Mitchell with the Academy.

"Danny has been out for a long spell, which I know has been frustrating for him, but he has worked hard on the training pitch, and is fitter than ever.

"It will be a case of keeping en eye on both of them over the next few days, then I will make my decision for Millwall."

Centre-back Nathan Clarke is to have an examination of his injured knee tomorrow.

A specialist will perform an arthroscopy on the right joint which was damaged during Saturday's match, after which Clarke left the stadium on crutches.

Clarke's younger brother Tom underwent a knee reconstruction operation on Monday and isn't expected to return to training until the Summer.
