Running back Adrian Peterson was named the NFC Offensive Player of the Week on Tuesday after rushing for 160 yards on 23 carries with two touchdowns in the Vikings' 24-10 victory over Detroit last Sunday. Peterson also had five receptions for 30 yards.

It is the fourth time in his three-plus NFL seasons that Peterson has earned the award.

Peterson's performance included a career-long 80-yard touchdown run, which ranks as the longest run by a Viking at Mall of America Field and is tied for the fourth-longest run in franchise history. It was Peterson's 21st career 100-yard game and 10th career run of 50-plus yards. Both are second in team history behind Robert Smith's 29 and 12, respectively.

Vikings look at four

The Vikings worked out four players on Tuesday, including two offensive linemen and two kickers.

The offensive linemen were tackles Scott Kooistra (North Carolina State) and guard Donald Thomas (Connecticut). Kooistra, a seventh-round selection by the Bengals in 2003, also has spent time with the Browns. Thomas was a sixth-round pick of the Dolphins in 2008.

The kickers were Hunter Lawrence (Texas) and Swayze Waters (Alabama-Birmingham). Lawrence went to training camp with Tampa Bay as an undrafted free agent but was waived. Waters had most recently been with Oakland.

It's common practice for the Vikings to look at street free agents during the week in order to get a first-hand look at them.

Pat doesn't hold back

Ask Pat Williams a question and you are likely to get an interesting answer. That was the case Monday when the Vikings nose tackle appeared on Sirius NFL Radio.

Williams was asked about the pushing and shoving that took place during Sunday's game.

"They were trying to play us tough," Williams said of Detroit. "They basically tried to cheap-shot us. They use hands to the face and were pulling us down." Williams also added, "I hate when guys act tough when they ain't tough."

The Vikings and Lions will meet again on Jan. 2 at Ford Field.
