Spencer, 30, is 6"3", 262, has played all of his seven seasons with the Cowboys after being the 26th overall selection out of Purdue in the 2007 NFL Draft. He had 32.5 sacks in 91 games with Dallas, recording a career-high 11 in 2012.
Spencer is still recovering from microfracture surgery on his ailing knee, which held him out of all but one game last season.
From Curtis Crabtree of PFT:
Spencer was given the franchise tag by the Cowboys in each of the last two seasons. He posted a career-best 11 sacks in 2012 before being tagged again by Dallas. As is the concern of any player playing under the franchise tag, Spencer suffered a serious injury that has now left him without the security a long-term deal would have delivered. Whatever team elects to sign Spencer this year certainly won’t give him a large contract with the concerns over his knee.
