Harbaugh remembers Thomas was part of an officiating crew that worked a Ravens preseason game last year. She will be a line judge for the 2015 season, the NFL announced Wednesday.
"She did a good job," Harbaugh said Wednesday. "She might be one of the better ones we've had. So, it's about time. Get these guys straightened out a little bit. Get some gals in there. She's a good ref, so it was a good choice."
Harbaugh said his approach with Thomas will not differ with how he deals with the other officials.
