Defensive end Nick Bosa, who left the 49ers’ game Sunday with what was described as tightness in his groin, was not feeling any better a day later.
Coach Kyle Shanahan said Bosa was still bothered by the condition and will be re-evaluated on Wednesday, when the 49ers return to practice at the Greenbrier Resort in White Sulphur Springs, West Virginia.
“You always want to use caution, especially with Nick on that type of stuff, but I know if we practiced today, he couldn’t go,” Shanahan said Monday on a conference call with Bay Area reporters.

“So I’m hoping he does better throughout this week. But it wasn’t feeling great today."
Bosa is tied for the NFL lead with six sacks this season. He was held without a sack on Sunday for the first time in his past eight games.
Bosa was held to one tackle while playing 26 snaps in the 49ers’ 37-15 victory over the Carolina Panthers.
