Erik Karlsson wouldn't guarantee his return to the lineup following Wednesday's practice, but it remains a possibility that he'll play before the end of the regular season. "We're just going to wait and see how things progress," he said. "I feel better and better every day, but it's still not back to normal and probably won't be for a long time." Karlsson may return from a 70 percent tear of his Achilles tendon in just 10 weeks, which is less than half the normal recovery time. His status for Thursday's contest at Washington should be clearer after the Senators' morning skate. Ottawa can clinch a playoff spot if they beat the Capitals.
