49ers cornerback Richard Sherman expected to undergo MRI on calf area

KANSAS CITY, Mo. -- Richard Sherman is expected to undergo an MRI examination on Monday to reveal the extent of an injury to his left calf area that sidelined him late in the first half of the 49ers’ 38-27 loss to the Kansas City Chiefs.

Coach Kyle Shanahan said the 49ers don't know the exact nature of Sherman’s injury. The cornerback sat out of practice Wednesday with what the team described as a heel injury.

"It is the same stuff that was bothering him going into it," Shanahan said. "It was the heel and calf area. They are all connected, lower extremity."

Sherman underwent season-ending surgery last year to repair a torn right Achilles tendon while he was with the Seattle Seahawks. He underwent offseason surgery to remove bone spurs from his left heel.

Sherman required assistance from two staff members to leave the field at halftime Sunday. He limped under his own power back onto the 49ers’ sideline at the start of the second half and back to the locker room after the game.

After the game, Sherman, who clearly was disappointed, did not speak to reporters as he left the team’s locker room to depart Arrowhead Stadium for the return flight back to the Bay Area.

Watch 49ers coach Kyle Shanahan recite his longest play from memory

If you're like me, you can't remember anything. This is the part where I say, "I can barely remember what I had for breakfast," but you caught me on a good day.

Toast with butter and strawberry jelly, and scrambled eggs -- with ketchup, because I'm weird. 

So when it comes to remembering an entire football play  ... well, that's why some of us play the sport -- and others just watch it.

Listen to 49ers head coach Kyle Shanahan recite his longest play:

Quarterback Jimmy Garoppolo has to memorize these types of plays, which is insane. Then has to relay the information to the huddle -- yeah I know, you know football. I'm just trying to remind you of the steps. But at least Jimmy G gets to repeat the play at least one additional time, right?

That should be enough.

I asked five-year veteran quarterback Sean Salisbury about the longest play he had to memorize in his NFL career.

"Explode to double right, Zoom, Scat right 585 Dodge, X Post check with me 60 outside. Double cadence on 2," Salisbury told NBC Sports Bay Area. "That’s one."

So Shanahan isn't the only "wizard" in this scenario -- or any of the scenarios. 

Chip Kelly 'not surprised' ex-49ers assistant prevented school shooting


Chip Kelly 'not surprised' ex-49ers assistant prevented school shooting

Chip Kelly knows the type of person Keanon Lowe is. It's why Kelly recruited Lowe as a football player at the University of Oregon, and years later had him on his staffs with the Eagles and 49ers as an assistant.

When Lowe prevented a school shooting Friday at Parkrose High in Portland, Ore., Kelly wasn't surprised at all. In fact, what the now-UCLA coach wanted to know was Lowe's form in going from a former receiver to a defensive player in a heroic act.

“I wanted to know his [tackling] technique,” Kelly said Saturday to Scott Osler of the San Francisco Chronicle. “He told me it was like when he was on kickoff coverage, it really didn’t matter how you tackled 'em as long as you got 'em to the ground.”

Lowe now is the head football coach and security guard at Parkrose. The school was on a 23-game losing streak when he arrived, and Kelly isn't surprised Lowe would step into a situation so far from the NFL.

"He’s just a special person that’s always wanting to help and serve," Kelly said. "He’s the type of kid you just want to be around him. He’s a special young man, and I think everybody is fortunate he was where he was yesterday afternoon.”

Lowe played two seasons under Kelly at Oregon. He made 18 tackles on special teams between his freshman and sophomore years.
