Coming off their road win over the Steelers, the Colts went home for a Week 11 AFC South rematch with the Houston Texans. In the first quarter, Indianapolis trailed early as Texans kicker Kris Brown got a 28-yard field goal. The Colts responded with kicker Adam Vinatieri getting a 40-yard field goal. Houston would answer with Brown making a 34-yard field goal. In the second quarter, Indy tied the game as Vinatieri got a 39-yard field goal. The Texans retook the lead as RB Ahman Green got a 1-yard TD run. Indianapolis closed out the half as Vinatieri made a 32-yard field goal. In the third quarter, the Colts took the lead as QB Peyton Manning completed a 23-yard TD pass to RB Joseph Addai. Houston would reply as RB Steve Slaton got a 71-yard TD run, yet Indy regained the lead as Addai got a 7-yard TD run. In the fourth quarter, the Texans tried to come back as Green got a 2-yard field goal, yet Indianapolis pulled away with Vinatieri nailing a 31-yard field goal. On the Texans' final drive, QB Sage Rosenfels was intercepted by safety Melvin Bullitt (who was filling in again for the injured Bob Sanders).

In April 1920 Poland launched the large-scale Kiev Offensive in hopes to capture Ukraine. Initially successful, the Polish Army started retreating after Russian counterattacks in early June 1920. Soon the Soviet forces began to threaten Poland's independence as they reached and crossed the Polish borders. On July 9, Polish Prime Minister Wadysaw Grabski asked the Allied Powers in the Spa Conference for military assistance in the war with the Soviets. The conference proposed that the Polish forces would withdraw behind the Curzon Line, the Soviet forces would stop 50km to the east of the line, the Lithuanian forces would take control of Vilnius, and all other disputes would be settled via negotiations in London. Grabski opposed the transfer of Vilnius, but under pressure of British Prime Minister Lloyd George, agreed to the resolution on July 10. At the same time Soviets and Lithuanians negotiated the Soviet-Lithuanian Peace Treaty, which was signed on July 12, 1920. Russia recognized Lithuanian independence and withdrew any territorial claims. The treaty drew the eastern border of Lithuania, which the Lithuanians continued to claim as their de jure state border until World War II. Vilnius Region, including Brasau, Hrodna, Lida, and Vilnius, was recognized to Lithuania. On August 6, after long and heated negotiations, Lithuania and Soviet Russia signed a convention regarding withdrawal of Russian troops from the recognized Lithuanian territory. However, the troops began to retreat only after the Red Army suffered a heavy defeat in Poland.
