The Bears made up for their Week 5 loss against the Lions by forcing six turnovers, and led 20-6 at halftime. Early in the third quarter, Major Wright and Charles Tillman returned interceptions of 24 and 44 yards, respectively, for touchdowns in a 1:52 span. This game was the first time the Bears returned two interceptions for touchdowns since the 1993 season, where they defeated Brett Favre's Packers 30-17. Tillman had a career game against Lions receiver Calvin Johnson, who led the NFL in touchdown receptions at the time. Tillman allowed Johnson to catch only seven out of 19 passes that were thrown his way. During the game, Bears nickelback D. J. Moore was ejected from the game after fighting with Lions quarterback Matthew Stafford, who had pulled Moore down by his helmet during Tim Jennings' interception return. The incident would eventually lead to a brawl between the two teams, and chanting from the crowd.
Question: How many catches did Calvin Johnson have?
Answer: 7
