Weaver has thrown a career-high 217 1/3 innings, and Haren is one-third of an inning away from matching his career high of 229 1/3. It would be hard to see Weaver sitting out, though, with a chance at the Major League strikeout crown potentially hanging in the balance.
It's possible one or both pitchers could make their starts, with a tighter than usual pitch count.
"We have other options, but we're not going to rule out these guys starting," Scioscia said. "We might start them and have them on a limited basis ... there's a lot of different options we have, but we do have arms in the bullpen that can piece together games. So you might have a bullpen day."
Weaver is scheduled to pitch Friday and Haren is scheduled to start the last game of the season Sunday. Both games are in Texas.
Ervin Santana, Saturday's scheduled starter, is in similar territory, 2 2/3 innings away from his career high of 219.
