The Seattle Seahawks have offered running back Marshawn Lynch a multi-year deal that would pay between $11 million and $12 million during the first year and $9 million during the second of what could end up being a three-year deal, according to multiple league sources.

Lynch's agent, Doug Hendrickson, and Seahawks general manager John Schneider met Friday night in Indianapolis, where the NFL scouting combine is being held. While the two sides are close on the framework for a deal, it's still not clear whether Lynch is inclined to accept it.

Lynch, who turns 29 in April, is entering the final season of his four-year deal that's valued at about $31 million. He is scheduled to earn about $5 million in base salary in that final year in Seattle. A potential extension would lift him above all NFL running backs in 2015 base salary except for the Minnesota Vikings' Adrian Peterson ($12.75 million).

It is believed that Lynch is considering retirement after eight seasons in the league, a move that wouldn't be a surprise, Schneider told reporters on Thursday in a news conference at the combine.

Head coach Pete Caroll was optimistic about Lynch's return, telling reporters Friday, "We've never thought of the future without him. Hopefully, it will work out."

Lynch was a catalyst for Seattle's offense last season, rushing for 1,306 yards and 13 touchdowns. In his last two games, the NFC title game and Super Bowl, Lynch ran for 259 yards and two touchdowns. It was widely viewed that he should've gotten a rushing opportunity on Seattle's final goal-line play in the Seahawks' 28-24 loss to the New England Patriots in Super Bowl XLIX.
