Brandyn Dombrowski is being placed on the reserved-injured list with a foot injury. #sdtc12— Ricky Henne (@ChargersRHenne) July 26, 2012
It's also possible that he seriously injured the foot during practice today, but I don't think they would've pulled the IR trigger on him this quickly. Most likely the doctors don't like the way that the injury has (or hasn't) healed.
Dombrowski has started 15 games over the last three seasons for the San Diego Chargers, playing every position on the offensive line except Center and Left Guard. He was expected to compete with Tyronne Green and Rex Hadnot for the LG position this year.
There are new rules for the Injured-Reserve List and here's a short breakdown of how they could apply here: If the Chargers decide to keep Dombrowski as part of the 53-man roster heading into Week 1, he would be able to rejoin the team after 8 weeks. If he's not on the 53-man roster, he would be ineligible to play at all this season.
Backup offensive tackle Brandyn Dombrowski is going on IR. Cyst on his foot. I believe it will be classified a non-football injury.— UTKevinAcee (@UTKevinAcee) July 26, 2012
Although the team has not yet put Dombro on IR yet (he just couldn't pass his physical this morning), they're still expected to.
