Kansas City, Mo ? A slimmed-down Ryan Sims finally went through his first practice Wednesday after agreeing not to seek damages if the Kansas City Chiefs are found guilty of collusion.

Chiefs’ president Carl Peterson said the National Football League players association signed paperwork Wednesday morning that put an end to the bitter, protracted struggle that had kept the first-round pick out of training camp and even caused Chiefs’ officials and Sims’ agent to take public shots at each other.

While Sims stayed out of training camp demanding more money as the sixth player taken in the first round, the NFLPA charged the Chiefs and Minnesota with collusion involving Sims and Bryant McKinnie, who was drafted right behind Sims.

When Sims and his agent finally agreed last week to a seven-year contract that includes a team-record signing bonus of almost $10 million, partly deferred to next year, the collusion issue was still hanging fire.

“Before our Management Council and the players association would sign off on this contract, they had to have an agreement and an understanding specific to Ryan Sims’ involvement or lack of in this collusion. That’s precisely what was the holdup regarding the contract,” Peterson said.

“They got it resolved (Wednesday) morning. So based on that, we went ahead and put him on the field.”

As far as the collusion investigation goes, Peterson said, “We have done exactly what our management council has asked us to do.”
