Warnings issued from Michigan:

The teams of #2-Brad Keselowski, #47-AJ Allmendinger and #88-Dale Earnhardt Jr. received written warnings for having to go through pre-race or pre-qualifying technical inspection three times at Michigan last weekend. It was the teams’ first warning under a new system where if a team gets four warnings between now and the end of the season, it will choose its pit stall last instead of where it qualified for the next race. Earnhardt will miss 15 minutes of practice time this week at Bristol because his car actually didn’t pass pre-race inspection three times Sunday. Also losing practice time this week are #27-Paul Menard and #32-Josh Wise for being late to the inspection line before qualifying.(ESPN)(8-19-2015)
