Somewhat surprisingly, the name of defensive end Dee Ford appeared on the list of today’s San Francisco 49ers roster moves. I say “somewhat” not because Ford has had ongoing back problems and this should have been expected, but because a team manager suggested the 49ers were looking at options for the veteran pass rusher.

San Francisco placed Ford on an injured reserve, meaning the player will have to miss at least three games, starting with this weekend’s game against the Arizona Cardinals. He is eligible to return for the week 12 home game against the Minnesota Vikings.

Ford appeared in the practice attendance report on Thursday with the back injury. He had missed the week 8 game against the Chicago Bears due to a concussion and has not appeared on an injury report due to his ongoing back problems since the week leading up to the season opener.

This week, chief executive John Lynch said the two injuries are not mutually exclusive.

“Dee has back problems,” Lynch said during his regular KNBR interview on Thursday. “When you’re dealing with someone, baseball, football, life and back problems, they can flare up from time to time. Even when he had the concussion protocol [last week]Yes, he was in protocol, so that’s it. Some of that, there was a play against Indy where he kind of fell, and it alleviated a bit of his back problems, and some of it was presented as concussion-type stuff. It’s kind of one and the same.

“So really not a new problem. It’s an ongoing problem with him, and we’re trying to work through that, see if we have him this week, and make some decisions. But Dee is a difference maker when he’s out there. The challenge was to have him out there.’

The next day, head coach Kyle Shanahan was asked about Ford’s back injury, which could plague the defender for the rest of his playing days.

“Yeah, that never went away completely,” Shanahan told reporters on Friday. “That’s something he’ll probably have to deal with forever. So something that’s back on, off again. The reason it’s mentioned for the first time is that we think it came with this concussion. Some of the symptoms are presented as a concussion [in Week 7] with the blow he got, but it played up some things in the back that were bothering him this week.”

The 49ers acquired Ford in 2019 through a swap from the Kansas City Chiefs. The pass rusher has defended five tackles, two tackles for a loss, four quarterback hits, three sacks and a pass in a limited role over six games this season. per professional football reference.
