The 49ers are calling their version of the Wildcat formation the Taser.
Wide receivers Michael Spurlock and Arnaz Battle took shotgun snaps in the formation Wednesday morning. Running back Michael Robinson, out with a groin injury, will also practice the Taser when healthy. All three players are former college quarterbacks.
"It was our first foray into it," offensive coordinator Jimmy Raye said. "There are some things about it that are different for us, and good. I like what I saw from Michael Spurlock. The initial introduction of it was very good."
Spurlock said he did not expect to run the Taser on Friday night when the 49ers open their exhibition season against Denver at Candlestick Park.
