Jordan Masterson will take on the role in Season 2.
In Season 1, Ryan -- the father of eldest daughter Kristin's son -- appeared in only one episode, making the stunt-casting of Jonas an easy decision. Season 2 is a different story. TVGuide.com reports the show is expanding the Ryan role to multiple episodes. Masterson (best known for the role of Dump Truck on "Greek") will take over Ryan's job of irritating Allen's Mike Baxter.
This isn't the first recast for "Last Man Standing" Season 2. Season 1's Kristin, Alexandra Krosney, will be replaced by Amanda Fuller ("Grey's Anatomy"). Meanwhile, Kristin and Ryan's young son, Boyd, will be aged up to age 5 and recast with Flynn Morrison. Previously, twins Luke and Evan Kruntchev shared the role.
"Last Man Standing" premieres Friday, Nov. 2 on ABC.
