Grant started the 2019-20 season with the Ducks, who traded him to the Philadelphia Flyers at the deadline.
The 30-year-old registered one goal and five points in seven regular-season games with the Flyers before posting a pair of assists in 15 playoff contests. He notched 14 goals in 49 games with the Ducks before the trade.
This will be Grant's third stint with Anaheim. He joined the club as a free agent in July 2017 before agreeing to a deal with the Pittsburgh Penguins one year later.
