BOURBONNAIS, Ill.--A week into training camp, the Bears have found some help on the interior of the line.
A league source said that the club will sign Donovan Raiola this afternoon provided he passes his physical. Raiola was waived Tuesday by the Arizona Cardinals. Of course, the team thought it had an answer to some depth issues earlier in the week when it claimed Maurice Miller off waivers from the Tampa Bay Buccaneers. He arrived and failed his physical.
Raiola, who played at Wisconsin, is the younger brother of Detroit Lions center Dominic Raiola. The Raiola brothers are boyhood friends of Bears center Olin Kreutz.
Donovan Raiola has also spent time previously in Pittsburgh and St. Louis.
The Bears have only 78 players under contract right now. After signing Raiola, they will have one more open spot.
UPDATE: Thanks to Brian McIntyre from macsfootballblog.com for pointing out that Raiola was also on the practice squad in Seattle last season.
