Arizona Cardinals announce 3 additions to the practice squad

The Arizona Cardinals announced a trio of signings, but only to the practice squad. We already knew about defensive tackle Christian Tupou, whose signing was made public on NFL transactions on Sunday. The other two players the Cardinals added were running back Dominique Williams and receiver Kevin Cone.

Tupou was claimed off waivers in May by the Cardinals and spent the entire preseason with the team. He was among final cuts over the weekend.

Williams (5-9, 205) joins the Cardinals from Minnesota where he was signed by the Vikings as a rookie free agent out of Wagner this past May. While at Wagner, Williams rushed for 4,435 yards, the third-most in school history while gaining over 1,000 yards in each of his final three collegiate seasons. His 4,435 rushing yards and 5,444 all-purpose yards rank fourth in Northeast Conference history and he rushed for 100+ yards in 26 of 43 career games.

I saw a report on Sunday that he was headed here and if you had followed me or the site account on Twitter, this was a signing that was reported by someone in Atlantic City. Williams himself said it wasn't true and it ended up being a funny exchange.

It turns out that the report was correct, just unconfirmed and not completely accurate -- he had to take his physical, etc.

His signing means NAU running back Zach Bauman is through here, unfortunately, for those that were rooting for him.

The Cardinals saw Williams in the preseason. He rushed twice for seven yards and caught pass for 11 yards.

He has 4.6-second speed, so he is not super fast.

Cone (6-2, 218) comes from Miami where he spent the preseason with the Dolphins after signing with the team on April 3. He played in all 16 games last season with the Atlanta Falcons and had one catch for 12 yards while contributing on special teams with seven tackles. Cone entered the league with the Falcons as an undrafted rookie free agent out of Georgia Tech in 2011 and played in 13 games over his first two seasons (2011-12) in Atlanta where he had three tackles on special teams.

Arizona has one remaining spot on the 10-man practice squad available.
