SANTA CLARA – Rookie linebacker Reuben Foster, who did not record an interception in his three-year college career at Alabama, picked off his third pass on Monday through four days of 49ers practices.
While he is still running with the backup units, Foster impressed coach Kyle Shanahan because of the way his interception Monday came about.
“The one he got today is the one I was most excited about,” Shanahan said. “It was the same (play) he had yesterday where it was a play action and he killed the fullback and went and tackled the back. The wide receiver was wide open behind him.

“He had the same play today, and he didn’t fill up in the run. He dropped back and got a pick. One play he got beat on bad yesterday and today we ran the same play at him and he got an interception. That’s what you want to see.”
Foster’s interceptions the past two days came against fourth-string quarterback Nick Mullens, an undrafted rookie from Southern Mississippi. Shanahan said there is no hurry to elevate Foster on the depth chart.
“We’ll let that play out,” Shanahan said.
The 49ers traded up to select Foster with the No. 31 overall pick.
