Patterson came down with a 53-yard pass from Matt Cassel in the opening quarter. He caught three of the five passes thrown his way for 71 yards and a touchdown, averaging 23.7 yards per grab.
Patterson is dealing with a foot injury that's kept him sidelined but coaches insist he won't be out long.
He injured his foot working out in California before training camp but is said to be close to being ready.
"He's improving every day," Zimmer told the paper. "I saw him do some stuff (Saturday). ... I'll be surprised if it's long (that Patterson is out)."
Offensive coordinator Norv Turner said Patterson, who missed practice Friday and Saturday, is "champing at the bit" to get going.
