Righthander Shaun Marcum is officially listed as day-to-day. However, manager Terry Collins acknowledged on Friday that the righthander's absence may linger on.

"With the discomfort he was in last week, I'm sure he will start out slow, so it could be another week to two weeks before we know where he stands," Collins said. "It's all about being able to get his arm up in a consistent release point. If the nerves are flaring up again, he's going to have a tough time doing it, which is going to cause some discomfort."

Marcum hasn't pitched since March 16 thanks to a variety of physical maladies, including inflammation in nerves in his neck and a right shoulder impingement. Marcum is on the disabled list with what the team is calling right biceps tendinitis.

Marcum, 31, had been expected to be activated to make the start on Sunday. Instead, lefty Aaron Laffey is expected to be called up. And the way it has gone for Marcum, Laffey may be staying for awhile.
