DaRon Bland has NFL-leading 8th interception for Cowboys after getting burned by Seahawks

Published Tue, 04 Mar 2025 08:15:34 GMT

ARLINGTON, Texas (AP) — DaRon Bland added to his NFL-leading interception total with a nifty pick, though that didn’t really make up for the big plays against the Dallas Cowboys cornerback before they rallied to avoid their first home loss this season. Bland didn’t return this one for a touchdown — he already has the NFL record with five picks returned for scores — but his eighth interception of the season late in the third quarter ended a streak of three consecutive TD drives for the Seattle Seahawks.“Nah, it ain’t nothing special,” Bland said about that pick. “I didn’t have a great first half. Try to make it up in the second half, that’s all it was.”The Cowboys failed to convert that into a go-ahead score, but Dak Prescott’s 12-yard TD to Jake Ferguson and ensuing 2-point conversion with 4:37 left propelled them to a 41-35 victory Thursday night. Seattle (6-6) entered the game without an offensive touchdown on its previous 20 possessions.That streak ended i...
