The 28-year-old, who joined the Lions as a free agent during the off-season, is expected to return from a knee injury to play against the Chicago Bears later today.
The Bears linebacker told the team's official website: "Reggie Bush is a talented running back.
"Not only does he run the ball well, but he catches the ball well. He runs well in space. He knows how to make defenders miss. He's a tough guy to also bring down.
"He can create mismatches if you split him out and put him against some linebackers. He's someone that you need to be aware of and know where he is on the field."
Bush has 115 rushing yards, 145 receiving yards and three touchdowns so far in 2013.
