PHILADELPHIA (973espn.com) - With the championship window perceived to be open, the Eagles aren't just settling when it comes to replacing injured defensive tackle Malik Jackson on the roster.

Philadelphia worked out veteran DT Akeem Spence, 27, Tuesday and inked the 2018 Miami starter to a one-year deal. Jackson, meanwhile, was placed on injured reserve in advance of Lisfranc foot surgery scheduled for next week.

Originally a fourth-round pick by Tampa Bay in 2013 out of Illinois, Spence (6-foot-1 and 307 pounds) has played in 88 career NFL games with 57 starts in stints with the Bucs, Detroit and Miami. Last season he started all 16 games for the Dolphins.

In South Florida, Spence played for then-Dolphins defensive coordinator Matt Burke, who is a good friend of Jim Schwartz and now a defensive special assistant for the Eagles. Spence joins a defensive tackle group which also includes Tim Jernigan and Hassan Ridgeway.

The Eagles also waived tight end Alex Ellis on Tuesday so they still have one open roster spot to fill.
