Fooch's Note: Reports from practice indicate Carswell suffered a right knee injury in practice. According to Barrows, his knee was wrapped in ice and isn't practicing.

The San Francisco 49ers made another minor transaction on Wednesday, as they signed wide receiver Brandon Carswell and released tight end Cameron Morrah. It was only two short weeks ago that I put together a 90-in-90 breakdown of Morrah. So much for that!

Carswell entered the NFL as an undrafted free agent last season, signing with the Oakland Raiders. He went through training camp with Oakland before being released. He was then signed to the practice squad, but released on Sept. 12. Carswell is a Bay Area native, having grown up in Milpitas and attended Milpitas High School, where he earned first-team San Francisco Chronicle All-Metro First-Team and San Jose Mercury News All-Area MVP honors. Good times!

According to Matt Maiocco, Carswell was in town for the 49ers rookie camp last month on a tryout basis, and reportedly looked good fielding punts. I suppose he will get a chance to compete for a special teams role.

Morrah missed some time last week with a hamstring injury, but reportedly was back at practice yesterday. His release removes one person from the backup tight end battle. Vance McDonald would seem close to a lock to handle No. 2 tight end work, but I'd imagine undrafted free agent MarQueis Gray will compete with Garrett Celek for that third tight end role.
