Whatever the reason for his change of heart, SportsLine.com has confirmed that the Detroit Lions defensive end on Tuesday agreed to the same four-year, $25 million contract extension that only one day earlier caused him to bolt training camp a discouraged man. League and team sources confirmed the agreement and Porcher is expected back in camp Tuesday afternoon.

The extension, which essentially results in a five-year contract since Porcher last week signed the one-year tender as a "franchise" player, includes a $10 million signing bonus. The agreement came even as Lions officials continued discussions over how to deal with Porcher's absence. It is not known yet if he will be fined for missing Monday afternoon's practice session.

If he is, however, Porcher certainly can afford the penalty.

Porcher was excused by coach Bobby Ross from the Monday morning practice to huddle with his agent and discuss a long-term offer the team made Sunday. But the eight-year veteran did not report for the afternoon session and, as of Monday evening, he had not returned to camp. Agent Ricky Lefft could not be immediately reached for comment Tuesday.

Porcher in February rejected a five-year, $35 million offer from the Lions that included a signing bonus of $13 million. He then changed his mind and tried to accept the deal, but the team already had sent the paperwork to the league designating him a "franchise" player. So that delay six months ago, in essence, cost Porcher between $7 million-$10 million.

A former first-round draft choice, Porcher has double-digit sacks in each of the past four seasons, and 50 sacks total over that period.

On a positive front, it appears Detroit quarterback Charlie Batch is poised to take the next step in his rehabilitation from a broken leg. Batch was examined Monday in Birmingham, Ala., by noted orthopedic surgeon James Andrews and was cleared for light jogging. There remains an outside chance Batch could be ready for the Sept. 3 regular-season opener at New Orleans.
