Sources: Mike Wallace mulls holdout

After Friday's deadline came and went without him getting an offer sheet from another team, Pittsburgh Steelers restricted free-agent wide receiver Mike Wallace is prepared to sit out offseason drills and at least the start of training camp, according to league sources.

Wallace told some within the Steelers organization that he does not plan to sign his first-round tender "until he has to," according to a source. This means that Wallace could wind up holding out for some or all of training camp.

"We're not worried about the reports," coach Mike Tomlin said at the team's pre-draft news conference on Monday. "He's still here. We will deal with it day-to-day."

General manager Kevin Colbert reiterated that Wallace remains in the team's future plans.

"Our intension has always been to sign Mike to a long-term contract," Colbert said.

Wallace is seeking a long-term deal and is unhappy with the $2.7 million first-round tender he received.

Wallace has until June 15 to sign it before the Steelers can cut the tender to $577,500 -- a loss of $2.1 million.

Steelers team president Art Rooney II has said the team wants to sign Wallace to a multiyear contract.

Wallace caught 72 passes for 1,193 yards and eight passing touchdowns last season, all team highs. In three seasons, he has 171 catches for 3,206 yards and 24 TDs.
