Extra Points: Clark, Cox, Rivers, Lions, XFL

In extending Russell Wilson, the Seahawks took care of their signature piece of offseason business on Tuesday. But more key contract negotiations loom, with Bobby Wagner entering a contract year and Frank Clark having yet to sign his franchise tender. It appears the trade talk surrounding Clark has not totally died down. This week has produced some chatter around the league about a Clark swap, Mike Florio of Pro Football Talk tweets. This comes shortly after a report indicated the Seahawks rebuffed outside interest in Clark at the outset of free agency and would only trade the impact defensive end if they were overwhelmed by an offer. Clark has said he will not report to Seahawks training camp without a long-term deal, so this obviously qualifies as a situation worth monitoring.

Shifting first to another NFC team’s defensive line, here is the latest from around the American football universe:

• Fletcher Cox confirmed (via Philly.com’s Les Bowen) he underwent an offseason surgery to repair a foot injury sustained during the Eagles‘ divisional-round loss in New Orleans. The procedure appears to have been done several weeks ago, and while Cox is out of a walking boot, the veteran defensive tackle looks set to miss Philadelphia’s offseason program. His goal is to return by training camp. Cox is coming off his best NFL season, which featured a career-high 10.5 sacks and his first appearance on the All-Pro first team.
• Also in the NFC East: Ezekiel Elliott did show up for the first day of the Cowboys‘ offseason program, Ian Rapoport of NFL.com tweets. So far, so good on the prospects of the Cowboys avoiding a contract-related holdout with their star running back. An Elliott holdout has been rumored, but for now, the fourth-year back is working out with his teammates.
• Conversely, Philip Rivers did not show up for Day 1 of the Chargers‘ offseason work, Eric Williams of ESPN.com notes (on Twitter). The 16th-year quarterback is entering a contract year, but the Bolts view him as an obvious extension candidate. Though, it is not certain if re-up talks have begun. Nevertheless, this does not appear to be a contentious situation.
• As the deadline for teams to wrap up pre-draft visits approaches, the Lions squeezed in a meeting with Clelin Ferrell, Dave Birkett of the Detroit Free Press notes (via Twitter). Detroit’s biggest offseason investment went toward its defensive end corps, in Trey Flowers‘ deal, but the Lions have met with other edge prospects as well. Both Brian Burns and L.J. Collier visited the Lions this month. Like Burns, Ferrell grades as a first-round-level prospect.
• Former Giants offensive coordinator Kevin Gilbride will resurface in the XFL. The 67-year-old coach will become HC for the XFL’s New York franchise, Jay Glazer of The Athletic tweets. Gilbride has been a head coach twice in his four-decade coaching career, leading the Chargers for 22 games between the 1997-98 seasons and overseeing the Southern Connecticut State program from 1980-84. Gilbride’s most recent NFL role was a seven-year stint as Giants OC, which ended in 2013.
