Teams across the National Football League recently conducted organized team activities, and while the biggest fantasy story of OTAs may have been the broken foot suffered by New York Giants wide receiver Hakeem Nicks there was plenty of news that could have an impact on the value of several Individual Defensive Players, including a significant injury on the defensive side of the ball as well.

That injury was suffered by Tampa Bay Buccaneers defensive end Da'Quan Bowers, who tore his Achilles' tendon while participating in OTAs on May 10th. Some had predicted a breakout sophomore season for Bowers, who started the last six games of 2011 for the Bucs after a knee injury delayed the beginning of his NFL career.

Now, with Bowers quite possibly out for the entire season another major injury has decimated Bowers' fantasy value, leaving veteran Michael Bennett as the starter (and a serviceable IDP DL3) at defensive end for at least one more season in Tampa.

Baltimore Ravens defensive end Terrell Suggs didn't tear his Achilles' at OTAs, but developments at Ravens OTAs may have shed some light on how the team intends to replace the reigning NFL defensive player of the year, who is out until at least November after suffering the injury while working out in Arizona.

When MyFantasyLeague.com released their latest set of positional eligibility changes at the beginning of May veteran Paul Kruger was listed as a linebacker while rookie second-round pick Courtney Upshaw was listed as a defensive end, which would imply that Upshaw would slide into Suggs' "hybrid" role and possess more IDP value.

However, Kruger lined up with has hand down at Baltimore's OTAs, while Upshaw was slotted at the SOLB, which would change matters significantly. Granted, this is a fluid situation that could change multiple times between now and opening day.

If things hold as they stand today more positional eligibility changes may be in store, and while Kruger's redraft fantasy value would receive a sizable bump as Suggs' replacement Upshaw's short-term IDP value will take a big hit if he stays outside on the strong side of the Ravens' 3-4 defense.

That wasn't the only IDP surprise of organized team activities, as Philadelphia Eagles defensive coordinator Juan Castillo pulled an interesting switcheroo at outside linebacker, installing rookie Mychal Kendricks as the first-team strong side linebacker over third-year pro Jamar Chaney, who had 92 tackles for the team in 2011.

Given Chaney's...

SLB Jamar Chaney (neck surgery) won't participate in the Eagles' mandatory June minicamp.

It appears Chaney jumped the gun when he declared himself 100 percent in late April. Chaney's absence means No. 46 pick Mychal Kendricks will operate as the Eagles' first-string SAM linebacker in next month's minicamp. Kendricks will be the favorite over Chaney for the job in training camp.

Jamar Chaney (neck surgery) is expected to shift to strong-side linebacker following the acquisition of MLB DeMeco Ryans.

Brian Rolle will stay on the weak side, leaving Akeem Jordan as the odd man out. Chaney will likely give way to Casey Matthews or Keenan Clayton on passing downs, limiting his production in IDP formats. Chaney expects to be recovered from neck surgery by training camp.
